A Drilling Method for Petroleum Geological Exploration

Abstract

The invention discloses a drilling method for petroleum geological exploration, comprising: S1, obtaining historical petroleum geological exploration data based on geological cloud, and preprocessing the acquired historical detection data to construct a historical detection data set; S2, based on The convolutional neural network constructs a geological type recognition model, and uses historical exploration data sets to train the geological type recognition model; S3, connect several optical fiber distributed sensors to the drilling device and perform drilling, and use the optical fiber distributed sensor to collect real-time data from exploration wells. Corresponding parameter data of the drill bit, and formation parameters are obtained based on the real-time acquisition of exploratory well parameter data; S4. Input the formation parameters obtained in real time into the trained geological type recognition model to obtain the geological type distribution of the formation, based on the geological type distribution of the formation, real-time Adjust the angle of the drill bit to complete the drilling. The invention can effectively improve the drilling efficiency, shorten the period of petroleum geological exploration, and reduce the exploration cost.

Description

Technical field [0001] The present invention relates to the field of petroleum geological exploration technology, in particular to a drilling method for petroleum geological exploration. Background [0002] Oil is one of the most important energy sources in the world, with the development of global social economy and the improvement of scientific and technological level, the demand for oil in the entire international community is increasing. China's oil exploitation can not meet the needs of domestic social development, which brings great pressure to the innovation and development of China's oil exploration technology, and the consequent development of petroleum resources is also a double pressure. In order to ensure the sustained and healthy development of China's national economic and social productive forces and the sustainable exploitation of China's petroleum resources, it is necessary to strengthen and innovate the exploration technology of petroleum geology and comprehensi...

Problems solved by technology

[0003] However, the traditional petroleum geological exploration technology has great defects in terms of maximum oil extraction and investment funds, and with the development of social economy, the quality of petroleum exploration and development is getting smaller and smaller. The disadvantages of exploration technology are becoming more and more obvious, and the continuous innovation of petroleum geological exploration technology has become a must for the development of the times

Especially in terms of drilling, since the oil exploration and development process is composed of many stages with different properties and different tasks, and in different stages, the purpose and tasks of drilling are also different. During the process, the wells to be drilled include: reference wells, profile wells, parameter wells, structural wells, exploration wells, data wells, production wells, water injection wells, inspection wells, observation wells, adjustment wells, which not only prolong the exploration period, but also extremely Greatly increased the cost of petroleum geological exploration
