The technology composition of technical solution of the present invention, see Fig. 5, Fig. 6 and Fig. 7.Technology shown in Fig. 5, Fig. 6 and Fig. 7 is divided into three parts: the sub-technology of work condition inspection is responsible for gathering creation data; The storage, management, analysis, judgement, optimization, calculating, warning etc. that sub-technology is responsible for data is optimized in quantitative analysis; Network browsing technology primary responsibility image data, calculation optimization analyzes the displaying of data, replaces the work that previous manual metering grade typing is shown.Technology shown in Fig. 5, Fig. 6 and Fig. 7 also can the technology such as compatible video or security protection, is the comprehensive solution platform in a set of digitlization oil field.

Theoretical indicator card and analysis thereof, see Fig. 9.Cyclic process: bottom dead centre A → loaded B → top dead-centre C → unloaded D → bottom dead centre A... →.ABC is upstroke static load change line.AB is loading procedure, and in loading procedure, travelling valve and standing valve are in closed condition; At B point loaded, distortion terminates, and plunger and pump barrel start relative displacement occurs, and standing valve is opened and sucks liquid.BC is suction process (BC=sP is throw of pump), and travelling valve is in closed condition.CDA is down stroke static load change line.CD is uninstall process, and travelling valve and standing valve are in closed condition; In the completion of discharge of D point, distortion terminates, and downward relative displacement occurs for plunger and pump barrel, and travelling valve is backed down, discharges liquid.DA is discharge process, and standing valve is in closed condition.
Oil well condition is diagnosed, and correct oil well diagnosis is the basis that oilwell produced fluid amount calculates:
Method one: effective stroke method.The method utilizes the ratio of the displacement of minimum load place and stroke, or utilizes merit figure down stroke straightway for effective stroke is to calculate oil well output.
Method two: area method.The method utilizes the ratio of merit figure real area and full (ideal) merit area of pictural surface as effective stroke, calculates oil well output.
Above method fatal defects:
(1), due to merit figure scrambling (such as merit figure down stroke is fluctuation), be difficult to determine effective stroke accurately;
Even if (2) effective stroke is accurately, but the factor affecting pumpage is not effective stroke, also has coefficient of fullness, pump leakage factor, solution gas coefficient.
Correct oil well diagnosis is the basis that oilwell produced fluid amount calculates: utilize computer diagnosis model can " fluctuation is serious " and ground merit figure, be processed into the pump dynagraoph than being easier to recognize, thus improve the accuracy of Diagnosis of Work Conditions of pumping.
