Abstract

The invention discloses a simulation experiment device for measuring a stratum invasion depth of a channeling sealing agent. The simulation experiment device comprises a hollow cylindrical sleeve, a kettle body which is arranged at the top of the sleeve and is fixedly connected with the sleeve, a base which is arranged at the bottom of the sleeve and is used for supporting and fixing the sleeve, a sand-filled pipe which is arranged in the sleeve along the axial direction of the sleeve, a perforation channel which is arranged between the kettle body and the sand-filled pipe and is used for communicating the kettle body with the sand-filled pipe, a compression module which is arranged in the sand-filled pipe and can slide up and down along the axial direction of the sand-filled pipe, and a jack which is arranged on the base and is used for driving the compression module to slide axially. According to the simulation experiment device, a booster pump is used for boosting inside the kettle body to simulate a process for injecting the channeling sealing agent on site under different pressure and displacement conditions so as to research the influence of the injection pressure and the displacement on the invasion depth of the channeling sealing agent; a test result is high in accuracy. The invention further discloses a measurement method of the simulation experiment device.

Description

technical field

[0001] The invention relates to the technical field of oilfield chemistry, in particular to a simulation experiment device for measuring the penetration depth of a channeling agent into formations, and also relates to a measurement method for the simulation experiment device. Background technique

[0002] With the continuous extension of the depth and breadth of oilfield development, the quality requirements for oil and water wells are gradually increasing, especially the implementation of subdivided layer injection-production technology and the promotion and application of tertiary oil recovery technology, the control of channeling between oil and water layers is becoming more and more important. are getting more and more attention. After a long period of production in oil and water wells, casing deformation, damage and leakage, coupled with poor cementing quality and interlayer conflicts caused by long-term water injection production, have led to increasing...

Embodiment Construction

[0033] The implementation of the present invention will be described in detail below in conjunction with the examples, but they do not constitute a limitation of the present invention, and are only examples. At the same time, the advantages of the present invention will become clearer and easier to understand.

[0034] Such as figure 1 As shown, a simulation experiment device of the present invention for measuring the penetration depth of the blocking agent into the formation includes a casing 1 in the shape of a hollow cylinder, a kettle body 2 fixedly connected to the top of the casing 1, and a casing 1 The bottom is used to support and fix the base 3, the sand filling pipe 4 arranged in the casing 1 along its axial direction, and the perforation channel arranged between the kettle body 2 and the sand filling pipe 4 to connect the two 5. A compression module 6 installed in the sand filling pipe 4 that can slide up and down along its axial direction, and a jack 7 installed o...
