Title:
EXPLOITATION METHOD FOR OPTIMIZING SPACING BETWEEN SHALE GAS WELLS
Document Type and Number:
WIPO Patent Application WO/2020/114387
Kind Code:
A1
Abstract:
Disclosed is an exploitation method for optimizing spacing between shale gas wells. The method comprises: determining the area of a block according to a geological structure acquired by means of exploration; analyzing a reservoir connection status, and determining a minimum exploitation area unit; calculating exploitable reserves in the unit, and determining a candidate target; acquiring a representative shale core, and performing physical property analysis thereon; using a multi-field multi-flow-state multi-scale unified mathematical model to calculate a seepage field and a pressure field; calculating an active exploitable area of each well; and performing well arrangement on the basis of the principle that the rate of inter-well interference is not greater than 10%. The method appropriately specifies spacing between shale gas exploitation wells while considering fluid-structure interaction, thereby effectively increasing shale gas production.
