RESULTS OF HYDRODYNAMIC RESEARCHES
Standard methods of fluid level build-up curve processing
have been used in preparing hydrodynamic well testing (HDWT) materials.
The practice of researches and the method of HDWT correspond a Guiding
Instruction 153-39.0-109-01. In its researches the Executor used its own measuring
facilities - electronic pressure thermal gauges MS-107, MTG-20M and sonic depth
finders "Mikon" and "Sudos".
- RESULTS OF HYDRAULIC LISTENING TO A WELL
The hydraulic listening to a well was carried out in accordance
with the request for proposal worked out for implementation of such a
kind of researches on terms of the request. The request and the project
for hydraulic listening to a well are in the Supplement 2. Recording of the
bottom-hole pressure dynamics in the well has been
fulfilled for 40 hours. The general view of the pressure dynamics recording
and a scheme of testing are in the Supplement 1.
- RESULTS OF FORMATION TESTING AND SWABBING IN THE
PRODUCTION STRING BY THE KII2M-95 SET
A combined scheme of jobs has been used there - testing plus swabbing.
Advantages of such a technology is the possibility of repeated
differential pressure creation by means of fluid lever lowering in tubing,
formation critical area cleaning, the most representative fluid samples
recovery as well as the correct determination of reservoir pressure.
- WELL TESTING IN AN OPEN BOREHOLE
The pressure build-up curve (PBC) has been processed by a Ryazanttsev's
modified method of Horner with account of borehole influence on the
rate of build-up pressure at the initial part of the curve (the after
inflow effect.) The period of inflow for the PBC processing in half-logarithmic
coordinates has been chosen from the fiishing moment of swabbing up to
the start of PBC and consists of 367 minutes.
- GASDYNAMIC RESEARCH RESULTS
Two pressure build-up curves (PBC) have been processed by the 'Sapfire' software.
The most probable formation models have been detected: 1. a model of endless formation
with double porosity 2. a composite model of endless formation...
