Definitions
- the invention relates to a method for fastening productive layers of a deep bore of the type specified in the preamble of claim 1.
- the liquid introduced into the borehole i.e. the drilling fluids and cement muds penetrate into the productive layer and deteriorate its storage or flow capacity, which extends the drilling time and requires additional measures to restore this storage capacity.
- Such measures are associated with a high workload and the use of expensive technical units.
- the invention is based on the object of a method for fastening or solidifying the productive layers of a deep borehole To show, which allows an increase in the inflow and filtration area while reducing the thickness of the insulating layer separating the productive layer from other layers.
- the impermeable casing can expediently be installed in the area of the productive layer together with the production tube tour, which saves additional work for the installation of the profile tube tour on separate drill pipes.
- the section of the bore lying in the area of the productive layer should preferably be expanded by a factor of 1.5 to 2.0 of the outside diameter of the production tube tour. If the diameter is increased by less than 1.5 times the diameter of the production tube tour, the inflow area for the liquid increases only insignificantly, while an expansion by more than twice the diameter of the production pipe tour is limited by the limit values of the maximum possible expansion of the profile pipes.
- the method for fastening the productive layer in a deep borehole is implemented as follows.
- the drill string is then removed together with the chisel and the scraper, and a production pipe tour is inserted into the drill hole, at the lower end of which a device for cementing and an impermeable casing made of profiled pipes are attached.
- the running in of this tube tour is stopped as soon as the profile tube tour is in the extended area of the productive layer.
- the impermeable profile tube tour is widened by injecting liquid into the interior of the profile tubes until the casing lies tight against the wall of the extended area of the productive layer, after which the production tube tour is cemented and the productive layer is opened up in a known manner by perforating the impermeable casing .
- the method is carried out with the aid of a device which has a drill string 1 (FIG. 1) with a chisel 2 at the lower end and a post-clearer 3 arranged above it with extendable clearing elements 4.
- Another group of equipment for carrying out the method (Fig. 2 and 3) contains a production pipe tour 5, at the lower end of which a device 6 for cementation is attached, which serves as a continuation.
- the device 6 has a transition 7 with wall openings 8 and 9, in the interior of which a bushing 10 is accommodated with a side opening 11 and a seat 12, which is secured against axial displacement by a pin 13.
- Profile tubes are connected to the lower end of the transition 7 to form an impermeable casing 14, which ends with a shoe 15 with a seat 16 and a ball valve 17.
- a ball 18 (FIG. 3) is provided, which is accommodated in the seat 12 of the socket 10.
- the productive layer 19 is drilled.
- the area of the productive layer 19 is widened by the extended broaching elements 4 of the post-clearer 3, this widening extending by 10 to 20 m to above and below this area.
- the production pipe tour 5 (FIG. 2) is retracted, specifically together with the impermeable casing 14 made of profiled steel pipes with longitudinal folds and the shoe 15 with the seat 16 and the ball valve 17.
- the transition 7, which basically represents the continuation of the production tube tour 5, engages with its lower end in the upper part of the impermeable casing 14 to such an extent that there is a mutual connection.
- the installation of the production pipe tour 5 is stopped. During the installation of this pipe tour, the liquid in the bore presses the ball valve 17 in the shoe 15 upwards and fills the cavity 21.
- a liquid such as drilling fluid
- a liquid such as drilling fluid
- Pumped pressure from 12 to 14 MPa and the impermeable casing 14 consisting of profile tubes is stretched to its tight contact with the wall of the enlarged area 20, so that the productive layer 19 is reliably separated from other layers.
- the pressure is released and the ball 18 (FIG. 3) is thrown into the production tube tour 5, which falls into the seat 12 of the bushing 10 arranged in the passage 7 of the transition 7.
- the liquid pressure is increased again, under the influence of which the pins 13 are sheared off, and the bushing 10 moves into its lower end position (FIG. 3).
- the liquid is displaced from the cavity 21 through the opening 9 into the annular space, so that the lateral openings 11 and 8 of the socket 10 and the transition 7 coincide with each other.
- the production tube tour 5 is then cemented using the conventional method, for which purpose cementing units (not shown) are used.
- the elements 10, 12 and 18 are drilled out inside the pipe tour 5.
- the production layer is then processed using known methods such as opened again by perforation of the casing, and the product is removed from the layer 19 through the holes 22 (FIG. 4) of the perforation.
