Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, hereinafter will by reference to the accompanying drawings the embodiment of the application be described in detail.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined mutually.
Fig. 1 is that angle of rake appearance schematic diagram is used in the pump punching of the embodiment of the present application, and Fig. 2 is the organigram of the production logging equipment of the embodiment of the present application.Production logging equipment shown in Fig. 2 comprises pump punching propeller as shown in Figure 1.
As depicted in figs. 1 and 2, the pump punching propeller 10 of the embodiment of the present application mainly comprises the first jointing 11 and the second jointing 12 be connected in logger string, and the hoop protuberance 13 between two jointings.
Hoop protuberance 13 between the first jointing 11 and the second jointing 12, external diameter is greater than the external diameter of the first jointing 11, is also greater than the external diameter of the second jointing 12.Therefore from axial, hoop protuberance 13 protrudes from the first jointing 11 and the second jointing 12.
As shown in Figure 1, the part between the second jointing 12 and hoop protuberance 13, is provided with circumferential groove 14.When applying, for arranging sealing O circle to seal in circumferential groove 14.
As shown in Figures 2 and 3, the first jointing 11 is connected with the fishing bell 21 in logger string 20 by screw thread, and the second jointing 12 is connected with the head harness body 30 in logger string 20 by screw thread.
The propeller 10 of the embodiment of the present application is connected between fishing bell 21 and head harness body 30, transfers in oil pipe 40 (transfer to when logging well in sleeve pipe in sleeve pipe 50) when production operation.During pumping, annular space is not closed below oil pipe 40 and between oil pipe 40 and sleeve pipe 50, pumping into mud and suppresses, mud being formed in sleeve pipe 50 and circulates above propeller 10 by suppressing interface 71 in oil pipe 40.The embodiment of the application is that the interface 71 of suppressing provided from the tee junction 70 between oil pipe 40 and cable sealing device 60 is suppressed in oil pipe 40, first joint splicing sleeve 50 (when logger string is logged well in sleeve pipe 50) of tee junction 70 or oil pipe 40 (when logger string is logged well in oil pipe 40), second joint stube cable sealing device the 60, three joint suppresses interface 71 for this.

1 2, significantly increase the active force of pump pressure, reduce down-hole be hampered card risk.
Because the external diameter of propeller 10 is larger than the external diameter of logger string 20, the gap smaller therefore in oil pipe 40 diametric(al), increases lifting surface area when pump rushes, thus smoothly instrument string 20 can be pumped to target zone.The embodiment of the application is not only applicable to reservoir performance monitoring (RPM) logging operation, is also suitable for the production logging operation that other are similar, as PLT, PNN, MIT etc.
The embodiment of the application connects a thicker propeller than logger string on the top of logger string, annular space between cable and oil pipe (supposing to log well in oil pipe) (below oil pipe and between oil pipe and sleeve pipe annular space do not close) is closed above logger string, down suppress above logger string with slush pump or well cementation pump, in sleeve pipe, set up circulation, thus reach object logger string being pumped to measuring well section.When logging well in sleeve pipe, angle of rake maximum outside diameter is larger, less than casing inner diameter than the external diameter of logger string.Under the prerequisite not affecting mud circulation, the ratio that angle of rake maximum outside diameter compares logger string external diameter is larger, and propulsive efficiency is higher; That is, under the prerequisite allowed, the ratio that angle of rake maximum outside diameter compares pipe aperture (when logging well in oil pipe) or casing inner diameter (when not using oil pipe and log well in sleeve pipe) is larger, and propulsive efficiency is higher.
The embodiment of the application make use of the relation between liquid force and lifting surface area, by increasing the external diameter of instrument string local, suitably reducing the gap between instrument string and oil pipe or sleeve pipe, increasing the lower thrust of liquid to instrument string.The embodiment of the application not only solves the situation of the card that to be hampered when instrument string is logged well in high angle hole, the more important thing is that encountering use when being hampered card when changing current operation has the usual thinking that the pulling equipments such as the crawl device of labyrinth solve problem, overcome for a long time in the technology prejudice that well logging production this respect is formed.
The embodiment of the application is unlike Drill-pipe conveyed wireline logging system or crawl device, carefully to check before every subjob that the communication of induction system or crawl device and performance, operation will carry out complicated servicing operations after complete, so just greatly simplify operation procedure, improve the safety and reliability of operation.The embodiment of the application breaks down or causes the probability of down-hole accident very little, and this is that Drill-pipe conveyed wireline logging system or crawl device are all beyond one's reach.No matter the embodiment of the application is log well in oil pipe or sleeve pipe, and no matter the external diameter of logger is large or little, can need to use special propeller according to well logging.
Although the embodiment disclosed by the present invention is as above, the embodiment that described content just adopts for the ease of understanding the present invention, and be not used to limit the present invention.Technician in any the technical field of the invention; under the prerequisite not departing from the spirit and scope disclosed by the present invention; any amendment and change can be done what implement in form and in details; but scope of patent protection of the present invention, the scope that still must define with appending claims is as the criterion.
