Abstract

Disclosed are a method and device for computer-based autonomous planning of drilling track for petroleum gas reservoir as well as a storage medium. The method comprises: acquiring a distribution image of petroleum gas reservoir (S101); converting the distribution image into a binarized image matrix (S102); constructing an evaluation matrix according to the binarized image matrix, and determining location points of petroleum gas enrichment regions on the basis of the evaluation matrix (S103); fitting the location points of petroleum gas enrichment regions to obtain a drilling track satisfying a preset curvature requirement (S104). The device comprises a distribution image acquisition module (131), a distribution image conversion module (132), an enrichment location determining module (133) and a drilling track fitting module (134). The method can improve the automation level and precision of drilling track determination for petroleum gas reservoir.

Description

technical field [0001] The present application relates to the technical field of oil and gas exploitation, in particular to a method, device and storage medium for determining drilling trajectories in oil and gas reservoirs. Background technique [0002] In the field of oil and gas, with the advancement of drilling technology, the number of directional wells, horizontal wells and lateral wells is gradually increasing, and the design of the drilling trajectory of the wellbore is gradually complicated. At present, the design of drilling trajectories is mainly carried out manually based on spatial geometric mathematical models such as circular arcs and cylindrical spirals; in some cases, this method can basically meet the requirements of conventional drilling technology. However, the efficiency of this method is low; and with the exploitation of unconventional oil and gas resources, the requirements for drilling technology are also increasing. need.
