Abstract

The invention discloses a ground device of a perforating fracturing testing system, wherein the ground device of the perforating fracturing testing system comprises a drilling ship (50) and a peroration device (10), a fracturing device (20) and a testing device (30), wherein the perforation device (10), the fracturing device (20) and the testing device (30) are arranged on the drilling ship (50), the perforating device (10) is arranged on the rear portion of the drilling ship (50), the fracturing device (20) is arranged on the middle portion of the drilling ship (50), and the testing device (30) is arranged on the left portion of the drilling ship (50). The ground device of the perforating fracturing testing system is arranged in one time, and capable of avoiding repetitive operations, improving operation efficiency, reducing operation time, and lowering operation cost.

Description

technical field [0001] The invention relates to the technology of offshore oil exploration and development, in particular to a ground device of a perforation and fracturing test system. Background technique [0002] In the process of offshore oil exploration and testing, when performing perforation and fracturing tests, three operations of perforation, fracturing and testing are carried out in sequence, and fracturing and testing may be performed repeatedly according to the realization of exploration wells, so as to achieve Exploratory well operations need. In addition, in the case that the formation cannot self-spray, it is necessary to induce blowout by gas lift, and the gas lift operation can also be repeated as needed. [0003] In the conventional operation process, perforation, fracturing, testing, and gas lift are independent operation processes. When performing one of the operations, it is necessary to arrange the operation device for this operation on the offshore p...
