According to the equivalent connectivity factor method,the fractures produced by the hydraulic fracturing measure are simulated by using interwell communication correction technique and local grid refinement technique.

A connectivity index called the relative connectivity coefficient was proposed to reduce the loss of analytic precision caused by network decompositions.

Knowledge based interwell oil layers' connectivity automatic correlation system;

Research of coverage and connectivity with sensor random deployment;

Digital pipeline network connectivity out of the analysis of the algorithm and implementation;

Design of Interconnecting Horizontal Wells and Wellbore Trajectory Control Technique;

To all points of a connected area on the image of the modular maximum value of wavelet transform at scale 2 2, the averaging grey value method is used to their grey values, then the edge of the dim place is continuous after the maximum variance threshold method is used.

The importance guide line of reliability network is the connection,reliability of communication network and how to organize the network when it was destroyed;through putting forward the mathematics model,which is convenient for analyzing and designing reliability communication network in a change of topology architecture.

In this paper, measuring principles of harness connection are analyzed and researched and a general harness measuring instrument is put forward including its implementation method and the design principle of hardware and software.
